IMPROVEMENT IN IVIACHINES FOR PICKING COTTON.

Specification forming part of Letters Patent No. 52,880, dated February27, 1866.

To all whom t may concern:

Be it known that I, WM. EDGAR PRALL, of Knoxville, in the county of Knoxand State of Tennessee, have invented a new and useful Machine forPicking Cotton and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in Which- Figure l is a side view. Fig. 2 is a view of asection. Fig. 3 is a vertical vsection taken through the center of theshaft. Fig. 4 is a view of a section ofthe cylinders. Fig. 5 is aperspective view of the toothed are.

Fig. l, A is a side vieu of the large Wheel, upon the perimeter of whichthe cylinders are arranged. B is a ixed grooved-Wheel on the outside ofA. O is a cam and hub, upon which A revolves. It is perforateddiagonally by an axle and xed upon said axle. A A in revolving upon thiscam are brought together at the bottom or such other point as may bedesired, according to the position of the cam C. D is an upright shaftadjusted at the bottom to the axle upon which R revolves and adj ustedat the top to the axle which perforates O. E is a small stationarygrooved wheel on the hub of R, and upon which a band from B Works. F isthe tongue 'of the running-gear and adjusted to the center of D. G isthe band which Works upon B and E. H is a shaft adjusted on D, to oneend of which is fixed a stationary band, I, running around A to I. I isa stationary band, against which the journals of N in Fig. 4 Work, whichcauses them to revolve. K is the driving-wheel of the machine.

Fig. 2, A is an inside view of the large revolving Wheels. F is thetongue of theV running-gear. L is the bed in which the cotton isdeposited after being taken oi' the cylinders. Mis a shaft adjusted onthe inside of L, and on the end of which the toothed arc m is xed. N isa hole in O in which the cylinders Work. f O is a piece around theperimeter and on the inside of A, and between Which and the edge of Athe stationary band runs. R is the driving-Wheel of the machine.

Fig. 3, A is the large revolving Wheel. B is the grooved. Wheel on theoutside of A. O is the cam upon which A revolves. D is the upright shaftconnecting the hub ofR and P. E is the small iixed grooved wheel on theinside of the hub of R. G is the band Working upon B and E. His a shaftadjusted to D, to which one end of O is fastened. M is the'bed in whichthe cotton is deposited. N is the cylinder of Fig. 4, around theperimeter of A. O is the stationary band from H to I, workin g againstthejournals of N. P is the axle conntcting the large Wheels.

Fig.4 is the cylinder around the perimeter of A, Which consists of alittle round brush With journals, upon .which the stationary band worksand causes them to revolve and catches the cotton as they come incontact with the boil. v

Fig. 5, L is the bed in which the cotton is deposited. M is the shaft onthe end of which the toothed arc is arranged, and which reverses themotion of the cylinders after they come from under the stationary band.The red lines represent the arrangement for cleaning the toothed arc.

I claim- 1. The revolving cylinders or shafts N, Fig. 4, covered withtenacious substance to attract and Wind the cotton from the bolls.

2. The revolving Wheels A, upon which the cylinders or shafts areattached.

3. The arrangement of a toothed arc, m, for reversing the motion of thecylinders and un- Winding the cotton.
